Abstract

A high efficiency ultrasonic surgical aspiration tip apparatus and accompanying method for surgical use. The apparatus has one or more substantially “V” or “U” shaped cuts in a contacting. The apparatus and method of use provides a cutting action at the contacting end when the tip is ultrasonically excited. The apparatus and method of use further provides a substantially uniform ultrasonic and aspiration field due to the positioning and shape of the substantially “V” or “U” shaped cuts. The aforesaid further allows a surgeon to position the ultrasonic generator handpiece at any rotational angle for provision of the benefits cited.
